Description
δU11=U1−U1
…
δU1n=U1−Un
導出された電圧低下に基づいて、次のように、各要素を通るシミュレートされた電流を判定することができる:
Is1=g11*δU11+g12*δU12+…g1n*δU1n
…
Isn=gn1*δUn2+gn2*δUn2+…gnn*δUnn
ここで、Isは、ネットワーク要素を通るシミュレートされた電流を表す。
Err(t)=(I1−Is1)2+…+(In−Isn)2
Err(t1…tk)=Err(t1)+Err(t2)+…Err(tk)
ここで、t1…tkは、時間期間を示す。
p=0.5*n*(n+1)
ここで、nは、判断基準の個数である。
p<0.5*n*50
ここで、計算は、推定された帯行列に基づく。上からわかるように、関係する網が50個を超えるノードを含むならば、疎結合を仮定することができると仮定する。この推定は、よい仮定であり、全体的に必要な計算を減らす。それでも、計算時間が問題ではない場合には、疎結合を仮定する必要はない。
Err1(t1)=(I1−Is1)2
…
Errn(tn)=(In−Isn)2
窃盗された電気エネルギの量に関する分析は、次の等式に基づく:
Ifn(t1)=(I1−Is1)
…
Ifn(tn)=(In−Isn)
図1に示された供給業者SPおよび3人の消費者C1、C2、およびCnを含む網に移り、コンダクタンス行列Gc内の要素が既に判定されていると仮定して、図4に示された表に示された値が、受信され、さらに処理されると仮定する。
配電網1内の1つまたは複数の供給の点(供給位置など)SPに関連する平均測定電圧値U1および平均測定電流値I1を、ステップ100で受信する。
